T0 ALL WHOM IT MAY CON CERN:

Be it known that I, FRANCIS B. SCOTT, of the town of Lancaster, andcounty of E rie, in the State of Neivas York, have invented a new andimproved Window-Screen; and I do hereby declare that the following is afull l and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

The nature ofmy invention consists in making a window-screen ofperforated card-board, supported in a wood or iron frame, as a -newarticle of manufacture. l

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I provide a frame similar to an ordinary picture-frame, (shown at A,)and taking a perforated card,.B, I damp it and setit in the rabbet ofthe frame, securing it in its place either with glue or setting in astop or bead. The card, by drying, is stietchedtiglit in the frame. Ifit should be necessary to letter or ornament cards have them printed byany known process applicable, (stone being preferable, not breaking thecard.) The card can be perforated either before the printing or after,and protected with a coat of varnish. For additional strength the cardscould be manufactured with threads running through every part thereof,or made to adhere to one side of it. The ordinary perforated cardpossesses suliicient strength for common purposes where cheapness is anobject. Y

Among the advantages gained by using the perforated cardboard one is thegreat difference in the cost. The advantages, 'all perceive, of having ascreen before a Window, admitting ventilation and excluding insects anddust, and allowing the inmates of the house to look out, in the daytime,without those outside being able to look in. v i

The perforated card-'boardV answers the purposes of a Wire screen, andin some respects is superior. It is difficult to paint the wire screen.The card can be manufactured of the color required, only requiring acoat of varnish to protect it. ALettering or landscapes, or groups offigures, can be printed on the card at a fraction of the cost ofpainting the same, on wire, and more beautiful elfects produced. Inlettering or ornamcnting a screen by hand, the perforated card, havingal flat surface, is-easier to work on than the uneven surface of a Wirescreen, and the colors show to a better advantage.

What I claim as my invention, and desire to secure by Letters Patent, is

A window-screen made of perforated card-board, and supported in a woodor iron frame, as a new article of manufacture, substantially asdescribed. i t
